I forgot to add battle mods, the other thread about sensors reminded me.
Here's two cupolas with sensors and LEDs installed instead of an apple. Can't be used with a club because of low profile, but are cool otherwise.
The StuG is actually using the periscopes, the sensors are below facing up for full 45 degree defense.
